We have performed hydrodynamic simulations of relativistic rotational supernova core collapse in axisymmetry and have computed the gravitational radiation emitted by such an event. The Einstein equations are formulated using the confor- mally flat metric approximation, and the corresponding hydrodynamic equations are written as a first-order flux-conservative hyperbolic system. Details of the methodology and of the numerical code have been given in an accompanying paper. We have simulated the… 
Gravitational Radiation from Axisymmetric Rotational Core Collapse
We perform a series of two-dimensional hydrodynamic simulations of the rotational collapse of a supernova core in axisymmetry. We employ a realistic equation of state (EOS) and take into account
General relativistic simulations of passive-magneto-rotational core collapse with microphysics

Gravitational Waves from Axisymmetric, Rotating Stellar Core Collapse
We have carried out an extensive set of two-dimensional, axisymmetric, purely hydrodynamic calculations of rotational stellar core collapse with a realistic, finite-temperature nuclear equation of
Three-dimensional simulations of stellar core collapse in full general relativity: Nonaxisymmetric dynamical instabilities
We perform fully general relativistic simulations of rotating stellar core collapse in three spatial dimensions. The hydrodynamic equations are solved using a high-resolution shock-capturing scheme.
